[vtk-developers] vtk Testing/Cxx and vtk Examples

[Bill Lorensen]

Marcus,

I think I have fixed them.

Each CMakeLists.txt in Examples need a
IF(NOT VTK_BINARY_DIR)
ENDIF(NOT VTK_BINARY_DIR)
around the
FIND_PACKAGE(VTK REQUIRED)
INCLUDE(${VTK_USE_FILE})

This permits the examples to be built outside of the usual vtk binary tree.

I may have missed some that I have not configured on my systems.
